has'for its object toprovide a new andimproved display or advertisingcard structure. e More specifically stated, itis an object of theinvention to provide an improved display or advertisingdevice wherein aprincipal advertising P or-display card has associated-therewith aseries of smaller circulars or the like, adapted to be individuallyremoved 01' disassociated' from the principal card structure. V

The inventio contemplates improved means for removably associating thecirculars withthe principal cardstructure.

, Further objects oftheinvention are to provide, in a structure ofthe-foregoing type, new and improved means for iacilitating the loadingof i the circulars upon'the principal structure, and

new and improved means for facilitating theinstructure constru.:i' ed inaccordance with the principles of the invention:

Referringymore, particularly to the drawing, in. Fig. 1 'thereqisillustrated apanel, generally, indicated bythenumeral III of a type andkind adapted to receive: display or. advertising card structuresconstructed inaccordance with the invention. Asshown; the panel isofthetype usually associated: with vehicles such as busses,

however, that thefinvention' is'appli'cable to dis-j play or advertisingdevices generally, and that thepanel or support structure accordinglymay be'mounted iIlLVELIiOllS types of installations.

More specifically, referring to Figs. 1 and*3. I thepanel structureincludes' an elongated sheet metalsupport I l, curved in cross section;and-pro vided at its opposite edgeswith inturned retentitan-flanges, i2and I3. A single; support H is adaptedtoreceive a plurality ofadvertising or it: may beeasily handled and snapped into-posidisplaycards/and to this end retaining bars M are provided atsuitableintervals, adapted'to en"- gage the end edges of the cards and retainthem in position against the surface of the support l I.

The side edges of the cards areretained within the flanges l 2 and l 3,these flanges thus cooperatinggwith the bars [4* to retain" the cardsfirmly against the curved surface of'the support I l The bars M- areformed of'sprin'g stockahd maybe removably engaged with-the flanges 12'and l3 and snapped into card retaining position as shown in Figsql and3.- i By removal of i the bars the cards may be'interchangedandreplaced;

The cardstructure, as, constructed in accordance with the invention, isillustrated in perspective detailin Fig.;2;the card being shown in itsnormal flat condition prior to assembly uponthe supportstructure. Thecardjstructure comprises,.m'ore specifically, amain'card memberl8and areinforcing or backing element l9,

pref erably arranged in one corner thereof, as illustrated. Thebaclringelement may be. adhesiveiysecured over its entirearea to the rear faceof the" card. A die-cut slot, generally indicated by, thenumeral 20, isperforated through both the main card and the reinforcing element. Theprovision. of the backing element enables the "main. card t8, preferablyof cardboard' or the like, to be made of'sufliciently light stockso thattion against the curved support structure I IL At Fig.8 of'the drawing.As shown, the slot corn- Fig. '7. is-..an;illustrative perspectiveviewof one 4 the same time the backing element produces an i area ofincreased strength and rigidity in the vicinityjoffthe slot 20; thebacking element, which i mayjalso preferably be of cardboard or thelike, inefiect producing a card of double thickness in j the vicinityofth slot; Y

The particular shaping of the slot, constitutinigia'nimporta'nt featureof the invention in one i offlitsaspects, is more particularlyillustrated in prises" a generally;jhorizo-ntal portion 2|, and a pairofd'ownwardly extending end portions 22 and 23;,the end andhorizontalportions cooperating to form an inverted generally U-shaped slotstructure. While the slot portion 2| is generally horizontallydisposed,it will be noted that it is not truly horizontal, but is curvedslightly, or sloped downwardly towards the ends. it will be noted thatthe horizontal slot is of progressively increasing width towards itscentral portion. The end slot elements 22 and 23 extend downwardly andslightly toward each other at their lowermost ends. Also, the lower endsof these slot elements are rounded or provided with arcuate terminalsurfaces. The particular shaping of the slot-is of importance ineffecting the objects of the invention, and its manner of operation, andcooperation with the other elements of the structure, is bestillustrated in Figs. 4, 5 and 6 of the drawing.

Referring to the illustrative views, Figs. 4 and 5, and first to Fig. 4,this view shows the card and backing element in section, and illustratesthe positions which the card areas in the vicinity of the slot tend toassume as the card is bent into generally arcuate or curved shape,corresponding to the curvature it will have when in assembled operativeposition. It will be noted that the card portion 24 disposed below thehorizontal slot portion 2| and between the end slots 22 and 23 will nottend to assume a curved position, but on the contrary will remainsubstantially straight as the card is bent. The card portion 24, beingunconnected from the upper card body by reason of the presence of theslot 2|, and also being somewhat structurally divorced from the adjacentside card areas and the bending forces therein by reason of the presenceof the slots 22 and 23, in effect forms a somewhat free tab element.Accordingly as the card structure is applied to its support II, asillustrated in Fig. 5, the tabor card portion 24, while being forced toassume a partially bent or curved position, does not assume the samecurvature or contour as the main card body. The tab assumes a lessercurvature and produces moreover at its upper portion 25, andparticularly adjacent the center thereof as indicated at 25' in Fig. 8,an area of increased pressure against the support II, and at its lowerportion-26, an area of decreased pressure. Uponthe proper proportioningof the parts for a given installation, the card portion 26 will separateitself slightly from the support structure U, as indicated in Fig. 5,and in any event sections of decreased pressure, as indicated at 26 inFig. 8, are provided to facilitate the introduction of circulars or thelike into the slot structure.

It will be seen that the slot 2|, when taken together with the card andthe backing support II, in effect forms a pocket structure into whichcirculars or the like may be inserted, and held in position between thecard and the support; The position assumed by the parts upon theinsertion Also,

zontal length of the slot 2| is slightly greater than the width of thecirculars, as illustrated in Fig. 3.

In operation the circulars are inserted as a packet or group into thepocket structure, and are thereafter removable individually by means ofthe extending tabs 36, as illustrated in Fig. 3. Due to the fact thatthe circulars are individual sheets, the supply within the'pocket may bereplenished at any time to the desired number, without removal ordestruction of the remaining circulars such as would be necessary if thecirculars were in book form or the like. As has been hereinbeforebrought out, the areas of reduced pressure 26 provide convenient entrypoints for the lowermost corners of the circulars, facilitating theirintroduction into the slot and pocket structure' Moreover, the generallycurved shape of the horizontal slot portion 2| permits the packet ofcirculars to be bent slightly as indicated by the dotted lines 37 inFig. '7, upon insertion. This, bending ofthe circulars imparts rigidityto theipacket, facilitating its introduction into the slot and into thecard pocket structure. While the circulars are held in the pocket, thecurved shaping of the slot portion 2| still tends to impart a veryslight curvature to the circulars aiding in retaining them in uprightposition. The circular extending tab portion 36 invites and facilitatesthe ready withdrawalof a circular, and at the same time discourages theremoval of more than a single circular at a time. The pocket structure,including the action'of the resilient retaining tab 24, as heretoforedescribed, and the general clamping action afforded between thereinforced card andthe backing support permits the withdrawal of onecircular of such circulars is illustrated in Fig. 6. As

that the circular comprises a main body portion 35 and a bent tabportion 36 adapted to extend downwardly and forwardly when the circularis in assembled position upon the card. The horiwithout the disarrayingor disturbing of the remaining circulars in the pocket. The backingelement I9 provides for increased strength of the card structure in thevicinity of the pocket, and the location of the slot 29 in proximity tothe retention flange I3 and the bar It permits these elements to impartthe'necessary supporting and retaining actionto the pocket structure. Inother words, the proximity of the support devices I3 and M to the pocketstructurev enables their supporting and retaining action to be impartedto the pocket, without causing the supporting forces to be transmittedthrough extended card surfaces such as would be true if the pocket weremore centrally disposed on the card.

The curved or arcuate surfaces at the lowermost extremities of the slots22 and 23 prevent tearing of the card and add durability-to theconstruction.
